Introduction
JetBrains has released IntelliJ IDEA 2025.3.5, a maintenance update that brings targeted performance improvements for Spring Framework projects. This release addresses a common pain point for developers who rely on rapid code completion and real-time analysis in their Spring-based environments. If you haven't yet upgraded to IntelliJ IDEA 2026.1, this version offers a significant boost in responsiveness without sacrificing the comprehensive features you expect from the IDE.
Performance Enhancements for Spring Projects
The key fix in version 2025.3.5 revolves around the automatic search for declared Spring beans. In previous versions, the IDE would trigger bean discovery searches during typing or code completion, which could cause noticeable delays in large Spring projects. This behavior has been optimized so that bean searches no longer interfere with everyday editing tasks. Code completion now runs smoothly even in complex dependency injection scenarios. The change is tracked under the issue IDEA-378966.
What Changed?
Previously, whenever you typed a bean name or triggered autocompletion, IntelliJ IDEA would attempt to resolve all declared beans in the project context. While this was intended to provide accurate suggestions, it often led to performance bottlenecks, especially in large applications with numerous Spring beans. In 2025.3.5, the bean search is deferred and only executed when explicitly needed, such as during a dedicated bean navigation action. This separation ensures that the IDE's responsiveness remains high during normal coding activities.
Benefits for Spring Developers
By eliminating unnecessary background searches, the update directly improves:
- Code completion speed – no more waiting for bean suggestions to appear.
- Typing responsiveness – keystrokes are processed without lag from background scans.
- General IDE fluidity – reduced CPU usage during editing sessions.
These improvements are particularly noticeable in projects that use extensive bean definitions, such as those built with Spring Boot, Spring Cloud, or multiple configuration files.
How to Update to IntelliJ IDEA 2025.3.5
Updating to the latest version is straightforward and can be done through several methods. Choose the one that best fits your workflow:
- In-IDE Update: Navigate to Help > Check for Updates (on Windows/Linux) or IntelliJ IDEA > Check for Updates (on macOS). The IDE will guide you through the process.
- JetBrains Toolbox App: If you use the Toolbox App, it will automatically notify you of available updates. You can also manually select the 2025.3.5 version from the list of installed tools.
- Snaps (Ubuntu): Ubuntu users can update via the Snap package manager with the command
sudo snap refresh intellij-idea-communityor the appropriate snap name for your edition. - Direct Download: Visit the official JetBrains website to download the installer or archive for your operating system.
Regardless of the method, ensure you back up your configuration (e.g., export settings) before applying the update, especially if you are customizing the IDE extensively.
Release Notes and Issue Tracking
For a comprehensive list of all fixes included in IntelliJ IDEA 2025.3.5, consult the official release notes. Beyond the Spring performance enhancement, this maintenance release includes minor bug fixes for code inspections, version control integration, and user interface adjustments.
If you encounter any problems after updating, please report them via the JetBrains Issue Tracker. When filing a bug, include relevant details such as your operating system, Java version, and a reproducible test case. The JetBrains team actively monitors these reports and often provides workarounds or hotfixes.
Conclusion
IntelliJ IDEA 2025.3.5 demonstrates JetBrains' commitment to real-world performance, especially for the large community of Spring developers. By decoupling bean discovery from typing and completion, the IDE becomes more responsive without compromising its powerful code analysis capabilities. If you are still on the 2025.x branch, this update is a highly recommended step toward a smoother development experience. Upgrade today and enjoy faster, more reliable Spring project editing.
